On the Superstability of the Pexider Type Trigonometric Functional Equation
Journal of Inequalities and Applications volume 2010, Article number: 897123 (2010)
We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: and, which can be considered the mixed functional equations of the sine function and cosine function, the hyperbolic sine function and hyperbolic cosine function, and the exponential functions, respectively.
